I've seen a few of the linear florescent lighting set ups which inspired (encouraged) me to think outside of the box I learned in so I'm trying only led grow lights for the rest of the winter unless I see signs of cold chams. So far it's brighter and about 10° cooler in the highest basking area from 90 to 80-82° and they seem to love it. I'm using 2 different lights one full spectrum led and the other 1200 lumens cool white energy bs led. I'm excited to see how the ficus trees react, so far the lizards are loving it and are super bright green. Prior to the switch I noticed alot of venting while basking in 85-90° im thinking the cooler nights have acclimated them to cooler winter temps. Veileds are fairly hardy when it comes to the more extreme highs and lows so I'm not to worried about them getting cold (I keep the heat set to 65° at night and first thing in the morning It bumps up to 73° so far the signals I'm picking up on say they are happy with the change. I started this thread for advice on or experience with no basking bulb. The full spec led does put off some heat the chams preferred basking under it prior to the swap out and still go to it now that's it's the warmer of the two. Ofcourse I'm still running my uvb florescent. The LEDs I'm using are 15 and 24 dollar lights the highest lumen output I could find locally. Online I've seen a few fair priced led bulbs that are very high lumen but ide be worried about blinding my chams. Does anyone know the safe max lumen for a veiled?
